Trial Outcomes & Findings for Swallowing Impairment After COVID-19 Infection (NCT NCT04537650)

NCT ID: NCT04537650

Last Updated: 2023-12-06

Results Overview

Frequency of participants demonstrating airway invasion on thin liquids, defined as Penetration-Aspiration Scale score of 3 and higher (Rosenbek et al., 1996). Higher scores indicate worse function.

Baseline Characteristics

Full Sydney Swallow Questionnare were missing for 12 participants in the non-ventilated and 2 participants in the ventilated group who reported no swallowing difficulties, and therefore did not complete the full questionnaire.
